| Abstract: | Based on stretch averaging, two non-affine strain measures for materials with random network microstructure are suggested. The first concept provides a scaling between affine and non-affine behaviour that is predefined by the network functionality. The second approach applies to fibres that experience strong reorientation upon macroscopic deformation of the network. (© 2014 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim) |
